在LHC上选择软衍射解离的方法

Methods to Select Soft Diffraction Dissociation at the LHC

Emily Nurse, Sercan Sen

摘要:

强子对撞机上的衍射事件的典型特征是探测器上没有粒子的区域,称为快度间隙。为了以这种方式观察衍射事件,我们考虑了在大型强子对撞机(LHC)的ATLAS和CMS探测器的前向区域的赝快度接受,并讨论了在sqrt(s)= 7 TeV的pp碰撞中选择软衍射解离的方法。我们表明,在有限的检测器快度接受,它是可能的选择衍射解离事件,通过要求在事件中的快度间隙,但是,它是不可能区分单衍射解离事件与双衍射解离事件与低衍射质量。

英文摘要:

Diffractive events at hadron colliders are typically characterised by a region of the detector without particles, known as a rapidity gap. In order to observe diffractive events in this way, we consider the pseudorapidity acceptance in the forward region of the ATLAS and CMS detectors at the Large Hadron Collider (LHC) and discuss the methods to select soft diffractive dissociation for pp collisions at sqrt(s) = 7 TeV. We showed that in the limited detector rapidity acceptance, it is possible to select diffractive dissociated events by requiring a rapidity gap in the event, however, it is not possible to distinguish single diffractive dissociated events from double diffractive dissociated events with a low diffractive mass.
